@ -244,17 +244,17 @@ At first, you may be tempted to use the following approach, which is wrong, as
it actually extracts all ``<p>`` elements from the document, not only those
inside ``<div>`` elements::
>>> for p in divs.xpath('//p') # this is wrong - gets all <p> from the whole document
>>> for p in divs.xpath('//p'): # this is wrong - gets all <p> from the whole document
>>> print p.extract()
This is the proper way to do it (note the dot prefixing the ``.//p`` XPath)::
>>> for p in divs.xpath('.//p') # extracts all <p> inside
>>> for p in divs.xpath('.//p'): # extracts all <p> inside
>>> print p.extract()
Another common case would be to extract all direct ``<p>`` children::
>>> for p in divs.xpath('p')
>>> for p in divs.xpath('p'):
>>> print p.extract()
